The Impact of Route Choice Modeling on Dynamic OD Estimation

This paper analyzes the effects of modeling errors when simulating the real route choice behavior on the solution of travel demand estimation. Firstly, several test networks have been adopted to address such issue, showing the sensitivity of the estimation accuracy to route choice parameters. Then, considering the real network case of Rome (Italy), the added value of using information on actual route choices as indirect measurements on the network (as mimicking OD travel times from e.g. Floating Car Data) has been demonstrated.
